One type is the percutaneous endoscopic gastrostomy (PEG) tube which is placed endoscopically. The position of the endoscope can be visualized on the outside of the person's abdomen ...
The tube is then marked at this level to ensure that the tube has been inserted far enough into the patient's stomach. Many commercially available stomach and duodenal tubes have several standard depth markings, for example 46 cm (18 in), 56 cm (22 in), 66 cm (26 in) and 76 cm (30 in) from distal end; infant feeding tubes often come with 1 cm ...
A gastrostomy can also be used to treat volvulus of the stomach, where the stomach twists along one of its axes. The tube (or multiple tubes) is used for gastropexy, or adhering the stomach to the abdominal wall, preventing twisting of the stomach. [2] A PEG tube can be used in providing gastric or post-surgical drainage. [6]
